A very bizarre issue we've been seeing (gifs below),

1. We have a presented View Controller that has a TeamBadgeView, which is a button that emits emoji as CAEmitterCells
2. Tapping this button lets users spam a fire emoji on their screen
3. Dismissing the presented view controller, and re-present the view controller, and now there is a delay. The more times I present/dismiss the view controller, the CAEmitterCell becomes more and more unresponsive
4. Confirmed that this is not a leak issue, the view controller and button are being properly deallocated
5. I have tried moving the CAEmitterLayer and CAEmitterCell around, holding a reference in the button, and declaring locally, but similar issues
6. Perhaps most bizarre, if I do not press the button at all, and simply present/dismiss the viewcontroller many times, and then press the button, there is a delay. The only time there isn't a delay is pressing the button on the first time the View Controller is presented
7. I have confirmed that the button's action is being fired correct, everytime I spam the button. It's just that the emitter cell is not rendering for a few seconds. And some of the emitter cells just don't render at all

It's gotten to the mind-boggling point, does anybody have any ideas or leads on what this could be?
